I'm not totally well versed on the subject, but i know for a fact the cheaper insurance goes to:
bikes with lower cc's and less power
bikes kept indoors (to make theft less likely)
bikes with alarm systems (again with theft)
bikes belonging to people in safe neighborhoods
bikes belonging to people with safe jobs (if you park at a construction site your insurance will be more)
so the bike itself isn't the main issue, but the less flashy and powerful the bike, the cheaper the insurance, but many other factors come into play

For liability only, a motorcycle is actually the cheapest to insure. For full coverage, fords are known to be inexpensive and volvo's as well because its been studied that volvo drivers are more responsible on the road vs. a mustang which is prone for getting in wrecks. I saw a list of actual specific cars/models that were the cheapest to insure. 1st is the Buick LeSabre followed by the Olds Silhouette, Honda Odyssey, Buick Park Avenue, Pontiac Montana, Mercury Grand Marquis, Buick Century, Chevy Venture, GMF Safari and Olds Bravada. The cheapest to insure will be a sensible, afordable, small sedan with the most safety features and the cheapest engine, trim.
